My Inspire 3 does not turn on at all once it turned off due to a flat battery. Naturally, I have charged it and reset it (held buttons for 10s while plugged to a charger). It just vibrates when it resets, but its screen persists off and furthermore I cannot sync with it.
I believed, that the battery protection circuit cut off voltage from its terminals and so it would be sufficient just to disassemble the Inspire and charge the battery directly. To my surprise, it gives 4.03V on its terminals. So the battery looks good.
Do you have other ideas? Or maybe it's a known issue?
Google Support tried to help, but ran out of ideas.
